Hi Wei, Lucene in general iterate through the index in the order of what is recorded in the SegmentInfos <https://github.com/apache/lucene/blob/main/lucene/core/src/java/org/apache/lucene/index/SegmentInfos.java#L140> And at search time, you can specify the order using LeafSorter <https://github.com/apache/lucene/blob/main/lucene/core/src/java/org/apache/lucene/index/DirectoryReader.java#L75> when you're opening the IndexReader
